Should I Repaint the Red Walls in Loft-Style Living Room?

Q: My husband and I are moving to an apartment that we are absolutely crazy about. It has a fantastic open floor plan, approximately 1300 square feet, and is built into the second story of a 1900s carriage house that is situated next to our to-be landlords' stone mansion. I love it for a million different reasons. My question relates to the color of the living room area.

The previous renter had painted the walls a dark red, which at first sight I didn't really like. Because it is a loft space, the ceilings are slanted in most of the rooms and the windows are few, limiting the natural light in certain areas of the apartment. My first impression was that the dark walls make the living room feel smaller:

Initially, I was thinking that by repainting the walls white or off-white, it would really open up the space even more and make it feel bigger. But on the other hand, as the color started to grow on me a little bit, I wasn't sure if repainting the walls white would complement the white slanted ceilings and dark wood accents (exposed beams and flooring) very well.

My decor style involves a lot of rustic metallics, wood, reds, purples and yellows, so I don't think the color of the wall as it is right now would clash with how I plan on styling the space.
